Finding unique ways to unlock the iPhone with jailbreak tweaks is all the rage. SmartTap brings a completely new way to access iOS while simultaneously draining battery power. By keeping the iOS digitizer activated while the display is dark, SmartTap can react to gestures or tapping even while the device appears to be asleep.
The best part about SmartTap is that everything is customizable, so users can decide what kind of tradeoffs they are willing to make to save battery power or enjoy expanded functionality thanks to the tweak. SmartTap makes it possible to double tap, swipe up or swipe down to either unlock the device, turn on the display, or launch an application.
Of course, if a passcode is set for security, the user will be prompted to enter the passcode before iOS unlocks or launches an app. Settings can be configured to allow the digitizer to sleep after a preset time interval, saving battery life. The tweak even makes it possible to double tap the home screen or lock screen to turn off the display. iOS will be locked, except the digitizer will be waiting for further input until the specified time interval elapses.
SmartTap is available from Cydia on the BigBoss repository for $1.99. Check here for instructions on how to jailbreak iOS 7.x with evasi0n 7. You can also find out how to purchase and install Cydia tweaks with this guide.
